" mowers 1 ont ,hffwn im ll,

un side. deviation of F5 Mm View @i @he same show a dl'ew tion. when thele'ver K is moved out of engagement with the shoulder L then it moves into an active position, to actuate the stop ping mechanism and thus bring'the loom to a I ner presently7 to be described in detail. The v Wire P Aof the electric circuit connects the electromagnets O with the metallic frame E of the loom, while the other Wire P contains avbattery Q and is connected with the shaft D* for the pulley D insulated by an insula` tion De from the metallic frame E. The flexible connection C'l is provided in part of its length with an insulation C which moves in Contact with the pulley D at the time the heddle frame A is raised, to insulate the flexible connection C for the ltime being, that is, until the heddle frame A is again moved to a lowermost position. as then the in` sulation C5 leaves the pulley D (see Fig. l). The iron B is connected by a wire P1 with the side arm A2, and one end of the bar G is connected by a Wire P3 with the other iron B', and consequently when the heddle frame A is in Aa lowermost position and the heddles I' are raised by .their warp threads J, as 'in'- dicated in Fig. 4f, then the top wall' I4 of the eye'I is out of contact with the barG and consequently the electric circuit is broken. 1When the heddle frame A is lifted by the lifting mechanism then the insulation C5 moves in contact with the pulley D', so that the lexible connection C' is insulated from and the side of the sheath G2, and as at this time the insulation C5 is out of contact with the pulley D it is eyident that the circuit is closed and the electromagnets O attract the larmature lever N, which in turn imoves the lever K out of engagement With the shoulder L', and when this takes place the stop mechanism of the loom 'is actuated to stop the loom.

In order to enable the weaver to readily detect which of the warp threads .I is broken,

i each heddle I is provided with a head I5,

preferably of Aornamental shape, as indicated in Figs. 2, 3 and 4, so that a dropped heddle I can be readily seen by the lower position of .adapted to be closed @eases its head I5 relative tothe heads l of the ad# jacent heddles (see Fig. 3).

Having thus described our invention, we claim as new and desire to secure by Letters Patent: l

l. In an electric warp stop ymotion for looms, means for stopping the loom when a warp thread breaks allowing its heddle to close an ylectric circuit, the said means including u insulated pulley, and a flexible lieddle'frame support of conductin` material passing over said pulley, the said` pulley and flexible support icing included in said circuit, the said flexible heddle frame support being provided with insulation on part of its length adapted to engage said pulley when the frame is raised.

2. In an electric stop motion'for looms, an electric circuit for controlling the stopping mechanism, and adapted to be closed by a fallen heddle when the heddle frame is in its lowermost position, the said circuit including ulleys, iiexible conductors passing Aover said pulleys and connected with the heddle frame and with the lifting mechanism for said frame, one if said {iexible conductors having an insulated portion adapted to move in contact with its pulley when the heddle frame is raised to insulate the said iiexible conductor from its pulley, the insulation leaving the pulley when the heddle frame is moved to a lowermost position.

3. In a device of the class described, means for operating the loom stop motion, `and a circuit for actuating the said means and y a fallen heddle when the heddle frame is 1n its lowermost position, the said circuit including the metallic loom frame, ulleys journaled on the loom frame one otP saidpulleys being insulated from the frame, flexible conductors assing over the pulleys and connected with tie heddle frame and with the lifting device for the heddle frame, oneo said flexible conductors being provided with an insulated portion adapted to move in contact with the pulley when the heddle frame is raised, the said insulated portion leaving the pulley when the heddle frame is moved to a lowermost position, and wires connecting the source of electricity with the loom frame and the shaft of the insulated pulley.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
